"Perfection is the enemy of 'good enough'" (Dr Guy Gratton, who aside from being a leading authority in aviation is also a Kempo Jujitsu 3rd Dan and friend of mine.)

What are your videos intended for? For my YouTube channel I use either my 6th generation iPhone or a non-HD Sony digital video recorder. They are far from professional standard but are good enough. The weakness is human (camrea shake) and environment (the sound of Badminton play) but not the image or sound quality. I use Windows Live Movie Maker to edit them.

If I was to record a professional DVD like Iain's then I'd be investing a few thousand in kit and expertise I think.

My son actually has a Nikon D3200 digital Camera (he bought it with his winnings from an international photographic competition - sorry proud Dad moment there), which provides really good video footage. We were playing around with it over the weekend - not karate.. a Zombie movie vignette with his brother and 2 friends (he is only 12... and I act like a 12 year old..).

I looked into the Final Cut Pro X, Motion and Compressor (as suggested by K0yhan), but it is I believe an Apple product, so not really suitable for my mainly PC-based home technology stack. If Iain you are using the native Windows Movie maker and getting the results you do... maybe I will invest some time and have a crack with that instead.

Again thank you all for your help ( I now have to crack on and get some story boards written and prepare the post-production work on Day-of-the-Evil-Night-Living-Dead-Dawn-Land (working title))
